If I had to point out a single aspect that keeps the pre-30 game fun, I would have to say that it's the totally eliminated down time between fights. Potion use, or "potting" as the locals put it, is a vital part of the game and the reason why healer classes are unnecessary enough for only one faction to get them. Potions are sold on NPC vendors for bargain prices, enough that it's easy to afford to keep 99-potion piles. >
